To all whom it may concern:

Be it known that I, ALBERT U. WALTER, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in .Spring-Lubrioator C-overs, of which the following is a description. reference being had' to the accompanying drawing and to the figures of reference marked therebn.

This invention relates to improvements in metal casin s for the laminated springs of vehicles; and 'more particularly to a metal casing extending longitudinally of the spring and serving as a protective casing and a lubricating meansfor the spring.

One of the db1ects of this invention is to provide such a casing in which the members thereof enclosing the spring have limited.

relativemovement to permit the free normal bending of the. springybut which parts will act to check any undue se )aration ofthe leaves, thus acting as a re ound clip.

Another object of this invention-is to provide a casing of the described-character in which the casing parts are held assembled, enclosing the spring by a simple means easily put together.

Yet another feature of this invention re= sides in formin thecasing of two telescoping sheaths, an providing means for resil iently lioldingthe sheathsassombled so as to permit the spring to flex normally, but

to not as a positive stop to check undue separation of the leaves of the spring.

A further object resides in coustrurting the member of substantially rigid sheet motal stalnping's, arid in the manner of fori'nmg the oil retaining cup as an integral part of the upper casing member.

These andiother ob ects wi ll in part be obvious and will in pa rtibe hcreinefte'r mor Referring to the" accompanying drawings Figural it a front view of an automobile show-ing 'the improved casing .in attached position; i

Fig. 2 is a perspective view of the complete casing;

Fig; 3 is a sectional view of the same as assembled asid Fig. 4' is aperspective-view of the bottom casing member.

In the drawings, I have shown my improvement as applied to a Ford car, and one end of one spring 1 only is shown. It will be understood, however, that the device may be readil shaped so as to be'appliedto'other types 0 cars. sheet metal bottom casing, or sheath 2 which is substantially U-shaped in cross section.

Said casing or sheath 2 has open ends and upstanding vertical walls 3 and 4 which taper from the end 5 to the end 6 to corre- J5.

spend to the tapering thickness of the laminated spring 1. Associated with this bottom casing or sheath 2 is a cover or upper easing member -7 which is likewise open at its ends andprovided with downwardly extending l0- the casing or sheath '2. The side walls 8 ltnd 1 9 areprovided with a rtures 15 and lo re-' '6 s ectively, which as s own are rectangular.

xtending through. the-apertures 15 mild 16 is char 17 the ends of which are provided with lips 18 and 19, respectively, which engage the outer face of the side walls 8 and 9 9 41nd prevent the side walls from spreadin which permits the parts tobe quickly and These lips also prevent the bar '17 from en wise movement. Rigidly secured-to the bar 17 is a leaf spring 21. Said spring is preferably-riveted to the bar as indicated at 20.

slightly larger than the cross section of the. 9

bar 17, which to other with the yieldin' sides permits the or to be readily insertc 1n the apertures or renjiovod therefrom In order to prevent. relative endwisc inovement of the upper and lower casings 2 and 7 95 the upper casin 7 has the metal 'of one end turned in slightly as indicated at '23 to provide a positive stop against which the end. of the inner casing member 2 abuts: This inturned portion on the upper casing T is at 1 the lefbhand end thereof as viewed in Fig; 1.

At any desired point, preferably near .the'

inner end thereofithe sheetinetal of the cov}; er of easing member'2 is drawn to form an to 25 orthe introduction of the lubricating oil. ,This oil cup projects outwardlyi Lo- The device consists of a G0 n gral oil cup 24 which is perforatedat ed 26. This pad is 1 )i-efera.bl v .J shaped so t at when laid about the springs, U01

the ends thereof throughout substantially abut and the is substantially encircled by the a In assembling the device, the rebound clip a is removed from the spring, as my telescoping members take the place of the rebound clip and perform the function thereof. The absorbent ed 26 is then laid about. the spring and isjpreferably tem orarily sel cured to the spring by means 0 a string or thejlike, after which the pad is soaked with lubricating oil. The bottom casing 2 is next placed under the spring and over the pad and the top cover placed over the sprm t5 and over the ad so as to enclose the-pad: the lateral we ls 8 and 9 of the cover or upper casing 7 lying outside of the lateral walls 3 and 4 of the bottom casing 2. The casings are then forced together and -.the looking but 17 carrying the spring 21 1s placed-in the apertures 15-and' 16. The leaf spring bears against the bottom 22 of tllie lower casing or sheath 2, and yielding y holds the two casing members in contact as with-the pad and the pad in contact with i the spring. The spring 21 permits the sections or casings to move relative to each other to accommodate the normal flexing or bendin offhe laminated spring." However, if the fioxing caused by rebound is undue, the bottom casing '2 willbe forced directly against the bar 17 which forms a positive stop to check further tendency of the leaves of the sprin to separate. In other'words', the spring, or 17, and rigid metal casin s function as a rebound clip fto'prevent t e spring from breikin I 7 When it is desir" tool] the springs-{it is not necessary to take the-casings '9. 'art. The oil is inserted th oughgthe port 5 in the oil cup 24.

It will e noted that the device and quickly assembled on a sprin 'It protects the spring from dirt an keeps it soaked in oil while presenting a neat attractive casing for the spring. The casings are firmly held in position so as to avoid all rattling and the device can be oiled without removing from the sprin s. so hile I have, d'escrib the leaf spring as supported by the bar carried by the side.

Having thus describe the invention, what I claim as new and desire to secure by Letters Patent, is 7 3 1.

In a device of the class described in combination .with a. leaf spring, a pair of trouglrshuped casings enclosing said s ring, one of said casings telescoping within the other, and means for holding said casing in assembled position, said means permitting said'casings to have a limited movement to accommodate the normal action of said s'prings, said means restricting jfurther relative movement of said casin s and constituting a rebound clip {or saif sprin' 3.
